Summary:
Effective control of nasal tip projection and rotation is a key component in modern rhinoplasty. Tip projection is a product of several anatomical factors: length and strength of lower lateral cartilages, the suspensory ligament, fibrous connections to the upper lateral cartilages, and the anterior septal angle. Several cartilage grafts have been described for effectively altering nasal tip projection and rotation. Columellar struts and septal extension grafts are both commonly used in modern rhinoplasty to affect projection and rotation of the nasal tip. Although columellar strut grafts have shown moderate efficacy in maintaining tip projection and unifying the tip complex, their effect on increasing tip projection has been shown to be very limited. In comparison, septal extension grafts have been shown to effectively control tip projection, rotation, and shape by securing the nasal tip to the septum. Varieties of septal extension grafts have been described to support the medial crura and control tip shape, all of which depend on the presence of a stable caudal septum. The type of graft used is dependent on the specific characteristics of the underlying tip structures. The authors’ aim is to provide an updated classification of cartilage grafts for altering nasal tip projection and rotation, and an algorithmic approach for their implementation. Although both columellar struts and septal extension grafts offer the modern rhinoplasty surgeon a way to alter tip projection and rotation, they do vary in efficacy. Understanding which graft to use and in what setting is key in successfully controlling projection, rotation, and shape of the nasal tip.
The ALT flap can emerge as the flap of choice for scalp reconstruction, even when proximal neck vessels are used as the recipient targets. Using a suprafascial dissection and extending the vascular pedicle to the profunda femoris artery can optimize its role in this setting. The ALT flap provides excellent cosmesis and durable scalp coverage with minimal donor site morbidity.

While the facial rejuvenating effect of botulinum toxin type A is well known and widespread, its use in body and facial contouring is less common. We first describe its use for deliberate muscle volume reduction, and then document instances of unanticipated and undesirable muscle atrophy. Finally, we investigate the potential long-term adverse effects of botulinum toxin-induced muscle atrophy. Although the use of botulinum toxin type A in the cosmetic patient has been extensively studied, there are several questions yet to be addressed. Does prolonged botulinum toxin treatment increase its duration of action? What is the mechanism of muscle atrophy and what is the cause of its reversibility once treatment has stopped? We proceed to examine how prolonged chemodenervation with botulinum toxin can increase its duration of effect and potentially contribute to muscle atrophy. Instances of inadvertent botulinum toxin-induced atrophy are also described. These include the "hourglass deformity" secondary to botulinum toxin type A treatment for migraine headaches, and a patient with atrophy of multiple facial muscles from injections for hemifacial spasm. Numerous reports demonstrate that muscle atrophy after botulinum toxin type A treatment occurs and is both reversible and temporary, with current literature supporting the notion that repeated chemodenervation with botulinum toxin likely responsible for both therapeutic and incidental temporary muscle atrophy. Furthermore, duration of response may be increased with subsequent treatments, thus minimizing frequency of reinjection. Practitioners should be aware of the temporary and reversible effect of botulinum toxin-induced muscle atrophy and be prepared to reassure patients on this matter.
Salvage mastectomy (SM) is the standard of care for patients with local recurrence (LR) after breast conservation therapy (BCT), often with immediate reconstruction. Complications of reconstruction are a concern for these patients, and long‐term data are limited. We sought to compare rates of complications requiring re‐operation (CRR) and reconstruction failure (RF) between autologous reconstruction (AR) and tissue expander/implant reconstruction (TE/I). Patients with locally recurrent breast cancer after BCT, treated with SM and immediate AR or TE/I between 2000 and 2008, were identified. CRR was defined as unplanned return to operating room for wound infection, dehiscence, necrosis (including flap, skin, or fat), hematoma, or hernia (for AR) and extrusion, leak, or capsular contracture (for TE/I). RF was defined as conversion to another reconstruction technique or to flat chest wall. This study included 103 patients with 107 reconstructions. Median follow‐up was 6.6 years. CRR and RF were significantly higher with TE/I (n = 34) compared to AR (n = 73) at 5 years (50.9% vs 25.5%; P = 0.02) and (42.1% vs 5.8%; P < 0.001). On univariate analysis (UVA), TE/I (HR = 2.14; P = 0.02) and diabetes (HR = 5.10; P = 0.007) were significant predictors for CRR. On UVA, TE/I (HR = 7.30; P < 0.001) and older age at reconstruction (HR = 1.03; P = 0.003) were significant predictors for RF. In this population of previously irradiated patients, TE/I was associated with significantly higher CRR and RF. Complications continue to occur up to 10 years after TE/I. AR should be considered in appropriately selected patients, though TE/I may remain a reasonable option in patients without high‐risk factors for surgical complications.
This is the first prospective study examining the FNR of fluorescence-assisted SLNB for patients with cutaneous melanoma. Our study reveals that this technique has one of the lowest FNRs published, especially considering the large percentage of participants with head/neck melanoma involved.
The posterior midline incision for the elevation of the medial gastrocnemius pedicled muscle flap allows for a safe, thorough mobilization of the muscle resulting in increased muscle reach and increased surface area when compared with the medial incision. Furthermore, the posterior midline incision provides better access to the gastrocnemius muscle origin and the lateral muscle head.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
